Application filed June 25, 1914. Serial No. 847,209.

To all whom it may concern I Be it known that I, CHRISTIAN DoRN, a

citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Bottle-Stoppers, of which the following is a specification.

The main object of my invention is to so construct a device for preventing the refilling of bottles as to insure a free flow from the bottle in pouring out its original conance with my invention to prevent refilling of the same after its original contents have been dispensed; Fig. 2 is a similar view showing the same in the tilted or pouring position; Fig. 3 is a-side elevation oft-he stopper removed from the neck of the bottle; Fig. 4 is a horizontal section on the line aa, Fig. 1, and Fig. 5 is a horizontal section on the line bb, Fig. 1.

In the drawing, 1 represents the neck portion of a bottle to which my improved stopper is intended to be applied, said neck portion having formedtherein, some distance below the mouth, an internal annular recess for the reception of a pair of split sealing and locking rings 2 and 3 of cork or other available material, which also engage with the tubular body 4 of the stopper and pre vent the removal of the same from the bottle neck, said tubular body 4 having at the lower end a sealing ring 5 of cork or equivalent material which will prevent the passage of liquid from the bottle around the body 4 and will cause all liquid escaping from the bottle to pass through a central aperture 6 which, when the bottle is in the upright or upwardly inclined position, is closed by means of a valve 7 shown in the present instance as a spherical bodv adapted to an appropriately shaped seat in the bodv 4 at the top of the aperture (3, as shown in Fig. 1.

In the side walls of the body 4 are formed two sets of openings 8 and 9 one above the Fig. 2.

other, and at the top of said body 4 is formed an internal screw thread towhich is adapted a corresponding external thread formed upon a cap structure 10 which, when screwed into the body4, confines the rings .2 and 3 to their seat on said body, as shown in Fig. 1.

:The cap 10 contains a chamber 11 which is closed at the bottom but communicates through openings 12' with the upper portion oft-he chamber within the tubular body 4, and from said cap member depend a series of elastic fingers 13 which constitute a cage for receiving and retaining the valve 7 when i the latter moves away from its seat on the tipping or tilting of the bottle, as shown in 3 The lower ends of the fingers 13 have projecting and tapering studs 14, as shown in Fig. 5, these studs-projecting into the openings 8 in the-walls of the body structure of the stopper and thus serving as ratchet teeth to prevent the unscrewing of the cap structure 10 when the same has been screwed into the body structure to its proper position in respect thereto, the inclined sides of the studs 14, by contactwith the forward 1 edges of the openings 8, causing thefingers 13 to be pressed-inwardly during'the forward movement of the cap but the abrupt rear ends of said studs 14 contacting with the rear walls of the openings 8 and preventing backward movement of the cap it an attempt is made tounscrewthe same.

The split rings 2 and 3 are free to expand or contract to a limited extent, and in applying the stopper to the neck of the bottle in the first instance the body 4 (to which the cork ring 5 has previouslv been applied) is inserted into the neck until it assumes its proper position therein, therings 2 and 3 being then contracted until they can pass through the neck of the-bottle above the annular recess therein, said rings expanding when they come into line with the recess so as to engage both the neck of the bottle and the bodv member 4 of the stopper and prevent the removal of the latter from said bottle neck. The valve 7 is then applied-to its seat in the lower portion of the body and iugs 8, 9 and 12, and the passage between the underside of the stopper body 4 and the underside of the bottle neckylinto the chain-i her 11, from which it flows into the neck of the bottle beyond the stopper and thence from the mouth of the bottle; Air entering the bottle through the upper openings 12, 9 and 8 and the aperture 6 takes the place of the liquid which is discharged, so that a continuous stream of considerable volume can be poured from the bottle during the entire time that the same is held in tipped or pouring position.

The holding of the valve 7 away from its seat by means of wires orother flexible instruments introduced through the chamber 11 of the stopper is prevented byvreason of the fact that the'openings 12 ot the cap are out of line with the openings't) in the body of the stopper and the-fingers 13 of the cap are in line with the openings 12 and in front of the openings 8 in the stopper body.

While I have shown split rings cooperating with an internal annular recess in the bottle neck asa meansot preventing withdrawal of the. stopper from said neck, other means may, if desired, be used for the purpose of locking the stopper in the neck of the bottle, and while I'prevent unscrewing. of the cap member of the stopper by causing the tapering studs at the lower ends of the elastic fingers 13 to engage with the openings 8 in the stopper body, an otherwise located ratchet device may, if desired, be-employed for this purpose.

Copies ofithis patent may be obtained for five cents eac l claim 7 1. T he combination of thebotue neck having an internal annular recess therein, a

stopper; a sealing. ring engaging said recess in the bottle neck and seated upon thebody member of the stopper, and a cap member for said stopper separate from the bodys member but locked'in. position thereinandf bearing upon said sealing ring so; as to re tain it in POSltIOII'llPOIl the bodymember.

2. The combination of the bottle neck having an internal :annular recess therein, a

stopper, a sealing ringengagingsaid recessand seated upon the body member of the stoppen a cap member separate from the 1 body memberof the stopper but screwed into :9

said bodyme'niber and serving to retain the sealing ring in position thereon, and a i ratchet device for preventing the unscrewing of said cap member;

3. Thec'ombinaticnnf the bottleneck havingan internal annular recess thereir'n... a r

stopper having a body member with? an inlet 7 passage and side openings; a valve for 1010sing the inlet passage, a sealing ring seated 7 upon said body member of the stopper and 3 engaging thev recess in the bottle, heck; and

a cap member separate from thebody member of the stopper but screwed into the same;-

said'cap member havinga discharge-passage therein and openings leading to said dis? 1 V charge passage,- and a valve-receiving cage consisting, ofspr1ng fingers having tapered studs for engaging withv theqside openings in the body member of the {stopper to prevent backward movement of saidcap; 1
